General system changes

Userland software is rebuilt with GCC 6. As old GCC 4 runtime libraries are still delivered to /usr/lib, automatic checks and cleanup is applied to remove harmful RUNPATHs (/usr/lib, /usr/lib/amd64 and so on) from binaries. illumos-gate is still compiled with patched GCC 4.4.

Kernel Page-Table Isolation (KPTI) was enabled to mitigate recent security issues in Intel CPUs (thanks to Joyent's Alex Wilson, John Levon, and Robert Mustacchi for their hard work on this).

GNOME 2 desktop was removed. A lot of applications were fixed not to depend on GNOME 2 libraries (including OpenIndiana-specific software like Network Auto-Magic GUI (nwam-manager), Time Slider and GUI installer).

Linked images support was enhanced to include zoneproxy support, so that ipkg zones without connection to Internet can update their software via global zone's proxy. Administration documentation is available in zones section of OpenIndiana Handbook.

MATE desktop applications are now delivered as 64-bit-only.

UPower was integrated.

Internet/Intranet Input Method (IIIM) was removed (IBus is kept).

Work on delivering 64-bit-only applications continues.

Note, that although shipped ISO and USB images support booting in UEFI mode, it's still work in progress. VGA console is not supported when system is booted in UEFI mode and installer still misses some steps to create bootable UEFI images.

UPower 0.99.7 and MATE Power Manager were added. ConsoleKit patches to support Suspend/Hibernate D-Bus API were backported. LightDM and MATE applications were updated to work with the new ConsoleKit functionality.

MATE was recompiled as 64-bit and applications updated to latest versions of 1.18 branch.

Firefox was updated to 52.7.3

VLC was updated to 2.2.8

Thunderbird was updated to 52.7.0

NVIDIA driver was updated to 340.106

Gnumeric was updated to 1.12.39

Note that PulseAudio is now delivered as 64-bit application and as a consequence its configuration files are now incompatible with the previous version. If pulseaudio fails to start after the update, just remove ~/.config/pulse directory.
